With user-replaceable batteries now (mostly) a relic of smartphones past, a lot of companies are making a big deal about how fast their handsets can charge up. Both Samsung and Motorola would have you believe their latest (and in Moto's case, upcoming) phones are best in class. But Tom's Guide rounded up a few recent flagships and found that it's actually the Asus ZenFone 2 that ranks best in the pack — depending on how you look at it, anyway. The Galaxy S6 ultimately hit 100 percent faster than the ZenFone, but it's got a smaller battery to top off. Asus also fared really well in the 15-minute test, so even a quick charge at your local Starbucks should buy you a decent amount of time.

Around 30 minutes in is when the S6 catches up to and eventually eclipses the ZenFone — and Samsung has recently said that the Note 5 charges at the same clip. That's pretty impressive when you factor in its 3,000mAh battery. One trend is clear; phones with some form of quick charge definitely outpace rivals like the iPhone and OnePlus 2. Battery recharge time isn't a leading factor in choosing which smartphone is right for you, but if the inexpensive Asus device checks off other boxes, at least you know it can juice back up with the best of them. Motorola says the upcoming Moto X Pure Edition leads the entire field here, so it'll be interesting to see how it compares come next month.
